To all whom it may concern..-

Be it known that l, ALFRED BROOKMAN, a subject of the Queen of Great Britain, at present residing in New York city, in the county and State of New York, have invented air Improved Apparatus for Printing on Glass or other Surfaces, of which the following is a full, clear, and exact description.

The present invention has for its object to provide an improved apparatus, especially adapted for printing designs of any kind on glass and analogous surfaces, although not restricted to printing on such surfaces, and whereby the printing of designs will be greatly cheapened, breakage of the articles being printed will be prevented, and clean and distinct impressions be obtained.

- The invention conslsts of certain features of construction and combinations of parts, that will be hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming a "part of this specification,

' in which similar letters of reference indicate corresponding parts in all the views.

Figure 1 is a side elevation of a machine constructed in accordance with my invention, parts being broken out and others shown in section.- Fig. 2 is a'plan View. Fig. 3 is an end elevation, the frame of the machine being partly broken away. Fig. 4 is a perspective view of the novel transfer pad with its frame and slide. Fig. 5 is an end view of one of the rollers; and Fig. 6 is a longitudinal sectional view of such roller.

In constructinga machine in accordance with my invention, the frame A thereof preferably comprises the longitudinally ranging sides a, a suitably braced by transverse connecting bars a, and at their upper edges at an the inside the sides a are formed with runs 4 aflon which are seated the beds 13,0 of which the bed B is ada'ptedto receive any suitable hide}: or plate Don which the design to be printed is'produced, andt'hebed Qis adapted he design is to" beyprinted. Onthe'under @3315, with jwh'icli:, mesh gear wheels'm li" a separate gear wheel tfor each'rack, saidwgear' wheels. being; mounted onshafts f, j'ihaving f for. imparting rotary moa suitable handle 0 repeive the glass orother article Eon-which side Teach 'hedB'and Cis provided with a rack tion thereto. Near each end of the frame a roller G, G is mounted, being journaled in suitable adjustable boxes g in the standards 9 that rise from the top of the frame, the standards being spaced apart suh'i'ciently to permit movement of the bed B or C under the adjacent roller.

Between the beds B, C, there-is mounted on the frame a slide H, to lugs 71. on which is pivoted a frame I, and in such frame is piv= oted a pad J, the pad having pivots j at its center which rest in the frameI, the pad J, having a-suitable rigid frame j" on which the pivots j are provided, and a filling 7' of print- '65 ers composition. The arrangement of parts is such that the frame I carrying the pad J may be rocked on its pivots to either the right or left, to cause the pad J to bear down on either the block or plate 1) or on the glass or other article E, and the pad J may be-turned in the frame I so that its composition surface 7' will be presented toeither the plate or block, or the article to be printed on. 7

In operation, the design is first produced on 7 5 the block or plate D and the same is suitably inked, after which the pad J isbrought down thereon, the frame Iof the pad preferablyoeing locked to the bed B, by passing'a pin a" through lugs don such frame and into the said bed. The shaft f is now rotated in theproper direction to propel the bed B with its block or plate and the pad J beneath the adjacent roller G, which will cause the pad to pick up the design. The motion of the shaft 8 f is thenreversed, to run the bed and pad back to their original position, the pad J is raisedand turned round, and brought downfon the glass or other article'E to be printed,.an d the bed 0 and pad run beneath the roller 9' and returned by proper movement imparted to the shaft f. The printed article is then'removed and replaced by another to be printed, and after again in king' the plate or block D, the method previously described is'r'epeated. 5 In this manner Igreatly redtice the cost of printing o glass and analogoussurfaces, the

' glass articles are preserved from breakage and .a clean and distinct impression is obtained. 7 The'rollers maybeadaptedfor'printing, 1n too connection with the movable beds, if desired,

.inwhich case the padis not employed, but the rollers are each formed as shown inFigs. 5 and 6, as follows: v

On, the shaft Z a core m is provided, prefl erably by building it up of disks as'shown in Fig. 6, and on such core an air cushion 'n' is wrapped and provided with any suitable device 'n' for charging it with air. Sllli0UIldiHg the air cushionn isa layer of canvas-0 or. any equivalent material, onwhich isa covering 10 of printers roller composition. The composition may beigiven a better surface when th.us.

formed in a thin layer, and it is given the desired yielding support by the air cushion 'n. Whenthe roller thus formed is employed for printing, the frame A. has an extension A,

and the. beds B, O, carrying'the inked plate orblo'ck and the articles to be printed, are

successively run under the roller constructed as describe r I Having thusdescribed my invention, I claim as new-and desire to secure by Letters 'Patent- 1. .In a machine for printing on glass and other surfaces, thecombination, of a suitable frame, rollers mounted thereon near. each end, sliding beds between the rollers, and'a transsaid beds and adapted to be locked to either of them 'to slide therewith, substantially as 3 5 described;

"3, In a machine for printing on glass and other surfaces, the combination, with two beds having independent sliding movement, and means for separately actuating the said beds, of a transfer pad pivotally mounted on a slide. arranged between the said beds, and adapted to be lockedto either of them to slide therewith, and rollers journaled in stationary bearings and adapted for contact with the transfer pad during the sliding movement thereof, substantiallyas described.
